difference between a segment and a page
In this thread, which was unfortunately closed, brewbuck states:
What's the difference between a segment and a page? And what kind of access controls do we have? Read/write? Anything else? How is memory protected?
Speaking of page tables and memory protection, some processors (e.g. x86) also have a memory protection mechanism called "segmentation" which uses segments instead of pages for access control. This shouldn't be confused with the kind of "segments" we are talking about here, although the two things are not entirely unrelated.
